Any reputable AMG servicing specialist dealers in Herts/Cambs area, my car is now 3yrs old and I don’t want to use Mercedes anymore, as they are robbing buggers and don’t do a good job 🤷♂️
I've always used Wayne Gates in Harrow for my E55 but my 2015 GTS goes to MB, I take your point regarding main dealers but think you're limiting resale if you take your GTS outside the network.
